FIGHT THE POWER

The New York agit-rap veterans are on tour this year commemorating the 20th anniversary of Fear of a Black Planet, the 1990 long-player that gave us one of Public Enemy's most enduring singles, "911 Is a Joke." Is it weird to see Chuck D and Flavor Flav hit the increasingly desperate heritage-act circuit? A bit, yeah. (Didn't "Don't Believe the Hype" warn us about stuff like this?) Still, PE's passion seems undimmed these days, something that can't be said of the group's ability to create material that stokes the pop-political consciousness. So, better we get recycled vitality than fresh marginalia, right? Sun., Aug. 15, 3 p.m., 2010
